There is no substitute for knowledge of the geology and paleontology of your preferred collecting area. Moving a few hundred yards can often put you in a different formation, especially in a faulted area like where I live. For instance tonight I took my boy to a construction site in the Pecan Gap chalk where I saw a recently dug deep pit. The gray chalk piles beckoned and a quick look turned up a large echinoid, probably a 2 inch Proraster dalli. Although the site was out in the open, apparently nobody had yet perused it. Flexibility in schedule and diligence won't pay out every single time, but on average the payoff is pretty good.
Danwoehr,
There are micro-teeth in the Pecan Gap Chalk. Have you even found any? Bruce Welton once sent me a couple of tiny squaloid teeth from it. I have wondered if anyone was still collecting in that.
